What is the difference between prokaryotic cells and eukaryotic cells?
What is eukaryotic cells have a nucleus and prokaryotic cells do not.
100
How do electron microscopes work?
What is that they use a stream of electrons that bounce off of the object and back to the microscope creating the image.
100
What does the cell theory state?
What is that ll living things are composed of cells, the cell is the smallest unit of life, and cells only arise from pre-existing cells.
100
What does hydrophilic mean?
What is water loving.
100
What is mitosis?
What is the division of the nucleus into two genetically identical daughter nuclei.
200
What purpose does the mitochondria serve in a eukaryotic cell?
What is they are the powerhouse of the cell
200
What is an organelle?
What is a compartment that is specialized to perform a specific role with a distinctive structure and function.
200
Anton van Leeuwenhoek developed better _______ and contributed to the development of the cell theory.
What is microscopes.
200
What is the main purpose of a cellular membrane?
What is to form a barrier through which ions and hydrophilic molecules cannot easily pass.
200
What are the four phases of mitosis and what is the correct order that they come in?
What is prophase, metaphase, anaphase, and telophase
300
What are some applications of stem cells in the medical field?
What is regenerating tissue,replacing lost or malfunctioning cells, or growing whole organs.
300
True or False: Prokaryotic cells have cell walls.
What is True
300
What did Robert Hooke do to contribute to the cell theory?
What is that he was the first person to identify and name cells.
300
What are the two groups of membrane proteins?
What is internal proteins and peripheral proteins.
300
What is cytokinesis?
What is the process in which the cell actually divides, in animal cells the cytoplasm pinches together and eventually splits.
400
What are the two properties of stem cells that make them so important to scientific research?
What is that they can divide indefinitely creating more cells/tissues and that they are not fully differentiated so can produce different cell types.
400
What is the process of prokaryotic cell division called?
What is binary fission
400
List the levels of anatomical organization in order: organism, cells, organs, tissues, and organ system.
What is cells, tissues, organs, organ system, and organism.
400
What is cholesterol?
What is a type of lipid that is neither a fat or oil but rather a steroid.
400
What are cyclins
What is proteins that help in cell division by binding to enzymes called kinases
500
How many distinctly different highly specialized cell types are there?
What is 220
500
What shape is prokaryotic DNA?
What is circular.
500
This theory explains the origins of eukaryotic cells.
What is the endosymbiotic theory
500
How do particle move across membranes?
What is particles move across membranes by simple diffusion, facilitated diffusion, osmosis and active transport.
500
What does cyclin A do?
What is activates DNA replication.
